- Boolean Conditions: Rust requires conditions to be
bool.
- No Implicit Type Conversion: Types are not implicitly converted in conditions.
- No Traditional
for Loop: Rust’s for loop iterates over ranges or collections.
- No
do-while Loop: Rust doesn’t have a do-while loop, but loop can be used to achieve similar behavior.
- Pattern Matching with
match: More powerful and safer than C’s switch.
- No Implicit Fall-Through: In
match statements, each arm is independent.
- Error Handling Without Exceptions: Rust uses
Result and Option types for explicit error handling.
- Exhaustive
if Expressions: Must cover all possible conditions when used as expressions.
- Variable Scope: Variables in Rust have stricter scoping rules, enhancing safety.
- No Implicit Variable Declaration: Variables must be declared before use, preventing accidental usage of undeclared variables.
